The Fallout Tactics demo is a freely downloadable playable demonstration of the gameplay of Fallout Tactics: Brotherhood of Steel. There are two versions of the Fallout Tactics demo: a single-player demo and a multiplayer demo.

The multiplayer demo adds a multiplayer component to the two-level single player demo. It supports both Gamespy Arcade and direct TCP/IP. Multiplayer games can be played either in "Assault" or in "Skirmish" mode.
